How to Check if a Date is Less Than Today Moment

If you want to check whether a given date is less than today's date, you can use JavaScript's built-in Date object.

Method 1: Using getTime() method of Date object

The getTime() method returns the number of milliseconds between the specified date and midnight January 1 1970. By comparing this value to the current date's getTime() value, we can determine if the specified date is less than the current date.

let givenDate = new Date('2022-06-10');
let currentDate = new Date();
if (givenDate.getTime() < currentDate.getTime()) {
    console.log('Given date is less than current date.');
} else {
    console.log('Given date is not less than current date.');
}

Method 2: Using comparison operators

You can directly compare two Date objects using comparison operators like less than (<) or greater than (>). When you use these operators, JavaScript internally calls the valueOf() method of the Date object which returns the number of milliseconds between the specified date and midnight January 1 1970.

let givenDate = new Date('2022-06-10');
let currentDate = new Date();
if (givenDate < currentDate) {
    console.log('Given date is less than current date.');
} else {
    console.log('Given date is not less than current date.');
}

Both methods give the same output, but the second method is easier to read and write. You can choose the method that works best for you.
